<H2>DESCRIPTION</H2><PRE>
These routines insert a character string (as many charac-
ters as will fit on the line) before the character under
the cursor. All characters to the right of the cursor are
shifted right with the possibility of the rightmost char-
acters on the line being lost. The cursor position does
not change (after moving to <EM>y</EM>, <EM>x</EM>, if specified). The
functions with <EM>n</EM> as the last argument insert a leading
substring of at most <EM>n</EM> characters. If <EM>n</EM><=0, then the
entire string is inserted.
Special characters are handled as in <STRONG>addch</STRONG>.
</PRE>
<H2>RETURN VALUE</H2><PRE>
All routines that return an integer return <STRONG>ERR</STRONG> upon fail-
ure and OK (SVr4 specifies only "an integer value other
than <STRONG>ERR</STRONG>") upon successful completion, unless otherwise
noted in the preceding routine descriptions.
X/Open defines no error conditions. In this implementa-
tion, if the window parameter is null or the str parameter
is null, an error is returned.
Functions with a "mv" prefix first perform a cursor move-
ment using <STRONG>wmove</STRONG>, and return an error if the position is
outside the window, or if the window pointer is null.
</PRE>
<H2>NOTES</H2><PRE>
Note that all but <STRONG>winsnstr</STRONG> may be macros.
</PRE>
<H2>PORTABILITY</H2><PRE>
These functions are described in the XSI Curses standard,
Issue 4, which adds const qualifiers to the arguments.
The Single Unix Specification, Version 2 states that
<STRONG>insnstr</STRONG> and <STRONG>winsnstr</STRONG> perform wrapping. This is probably
an error, since it makes this group of functions inconsis-
tent. Also, no implementation of curses documents this
inconsistency.
